HOSE-WRENCHES.

A Specification formingpart ofLettcrs Patent No. 144,827, dated Novenbtr25, 1873; application filcd November 5, 1873.

A To all whom it may concern:

Be it known that I, EDWARD BUCKLIN, J r., of Pawtucket, in the county ofProvidence and State of Rhode Islandyhave invented certain Improvementsin Hose-Wrenches, of which the following is a specification:

My said invention relates to a device for coupling and uncoupling hose,and for other purposes; and consists of a jointed clutch, having aperforation in either arm, and the upper half of said jointed clutchhaving a short rearward extension, resting upon a spring, the wholebeing attached to a handle to facilitate its use.

The accompanying drawing is hereby made a part of this Specification.

a is the handle, and b c the arms of said jointed semicircular clutch. d0 Show the perforations in the ends of the arms b c. f is the jointwhich unites the upper and lower halves or arms of said clutch; and g isthe short rearwardextension from the upper half or arm; h is athumb-rest on the end of said extension g; and i a spiral spring, oneend of which is inserted in a hollowed place in the handle a, and theother end supporting the part g. The said respective parts may be madeof iron or other suitable material.

It is well known that hose-couplin gs are p'rovided with two short knobsor protuberances. In the use of said invention it is designed to fit thearms b 0 onto said knobs or protuberances by means of the perforations de. In applying the device the upper half or arm of the clutch is raisedby pressing on the thumb-rest h, and, after the said knobs orprotuberances are fitted into the arms 0 d, as aforesaid, the pressureis removed from said thumb-rest, and

down upon the coupling of the hose, and firmly ing is entirelycompleted. The Wrench is easily and quickly removed from the hose bypressing upon said thumb-rest, and raising the upper arm or half of saidclutch, as afore described.

One of the great defects of the old wrench consists in its inevitabletendency to slip 011' the coupling. The above-described device entirelyobviates this annoying difficulty by firmly securing the arms to thecoupling when the wrench is used.

I do not confine myself to the use of a spiral spring under the part 9;any other form' of sprin g may be used for the purposes described.

I claim as my invention, and desire to secure by Letters Patent- Ahose-wrench composed of a jointed semicircular clutch, having the endsof the arms thereof perforated, as shown, and having the rearwardextension g and spring i, all substantially as'and for the purposes setforth.
